1 tv cost = 2 * 201 = 402 $ ;

Answer 2

Answer:

Final answer:

To solve the problem, you set up two equations based on the information given. Then, you substitute one equation into the other to solve for the cost of the TV, which comes out to be approximately $405.43.

Explanation:

To answer this question, you need to use algebra. We can create two equations based on the information given. Let's say the cost of a TV is x and the cost of a DVD player is y. According to the problem, we have two equations:

2x + 3y = $1421 (This comes from the total cost of the 2 TVs and 3 DVD players)
y = 0.5x (This comes from the fact that the cost of a DVD player is half the cost of a TV)

We can then substitute the second equation into the first to get:

2x + 3(0.5x) = $1421
2x + 1.5x = $1421
3.5x = $1421

To find the cost of the TV 'x', you can divide both sides of the last equation by 3.5 resulting in x = $405.43. So the cost of one TV is approximately $405.43.

250% increase of 28,000?

Answers

250% can be converted into a fraction 250/100 or into a decimal 2.50.
so 250% of 28,000 is 2.50 times 28,000 which is 70,000.
28,000 is increased by 70,000 to 98,000

In math "of" means multiply (x). So 250% increase of 28,000 means

250% x 28,000 + 28,000 (we add 28000 because it's an increase so we have to add it to the original amount).

250% x 28000 =
2.5 x 28000 = 70,000

Now add it back to the original 28,000

70,000 + 28,000 = 98,000
